Solution Overview

Problem

Current ephemeral architecture devices for events are costly, complex to assemble, and lack the ability to be made from recycled materials, making them unsuitable for low-budget cultural events that require durable, transportable, and easily assembled structures with high user capacity and projection capabilities.

Innovation Solution

A transportable container dome made from recycled aeronautical equipment, specifically the envelope of a hot air balloon, using high-strength synthetic fabric with alternating colors, inflatable design, and counterweights for stability, allowing for easy assembly and disassembly without entry/exit points, and serving as a projection screen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional tents or pressostatic structures are used, then user capacity and protection function are improved, but device complexity and cost increase significantly

Engineering Contradiction:
Improveuser capacity and protection functionVSAvoidassembly complexity and cost
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The dome is divided into multiple fabric panels that are independently connected through stitching patterns. These panels can be separately manufactured, transported, and assembled, reducing the complexity of handling a single large structure while maintaining the overall integrity and user capacity of the dome.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention uses a single-layer flexible fabric dome instead of rigid frames or complex pressostatic structures. The fabric material provides both structural integrity and protection functions while being lightweight, easy to transport, and simple to assemble, directly reducing device complexity and cost.

Inventive Principle:
Principle #30Flexible shells and thin films

2Strength

If inflatable structures are used, then durability and protection are improved, but assembly complexity and cost increase

Engineering Contradiction:
Improvedurability and protectionVSAvoidassembly complexity and cost
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The dome incorporates an inflatable base perimeter that provides structural support and stability. This pneumatic element is simple in design, requiring only air inflation to achieve the desired structural effect, avoiding complex mechanical assembly while maintaining durability and protection.

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The invention uses a flexible fabric structure that derives its strength from the inflatable base and the tension created by the dome shape, rather than requiring rigid frames or complex pressostatic chambers. This approach maintains durability while significantly reducing assembly complexity and cost.

Inventive Principle:
Principle #30Flexible shells and thin films

3Strength

If conventional materials are used, then structural integrity is maintained, but environmental impact and cost increase

Engineering Contradiction:
Improvestructural integrityVSAvoidenvironmental impact and cost
Core Design Contradiction:
StrengthVSLoss of substance

Solution Approach 1:

The invention prioritizes the use of recycled materials, specifically recycled nylon, in the construction of the fabric panels and structural elements. This recovery and reuse of materials maintains structural integrity while reducing environmental impact and material costs.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The dome utilizes composite material construction, combining recycled nylon fabric with inflatable structural elements. This composite approach creates a structurally integrity structure while maximizing the use of recycled materials, thereby reducing environmental impact and overall cost.

Inventive Principle:
Principle #40Composite materials

AI summary

Ephemeral architecture device constituted by a dome-shaped receptacle (1) of high strength fabric and a single layer consisting of a multitude of fabric panels (2) artistically sewn together in alternating colors, which in turn comprises sections of independent segments (4) also integrated through sewing. The dome in turn includes: one or more air inflation ports (8) located at the ground level, in which there is coupled in each case one air blowing device such as a fan (9); and a perimeter skirt (6) located along its lower edge and bent inwardly, positioned parallel to the ground on which it is installed, over which a multitude of counterweights (7) are strategically placed along the perimeter.
